I hope youre right man, im experiencing the same, too incidental 'break in/stuck' period with my trackpad from my new 2,4 MBP

I'm confident we would have heard complaints if the sticky trackpad remains for long. My PB G4 trackpad has a section that's literally as reflective as glass by now - either it's worn down to be smooth, or my happyfingergrease has established a nice little slippery pond in the middle. Either way, it's like tracking over ice (toasty warm ice, that is.)
